Apparatus for separating solvent in a feed of solvent and deasphalted oil produced in a deasphalting process includes a feed line (1) for receiving the feed and constructed and arranged to produce a stream (10) of fluid containing supercritical solvent and deasphalted oil. A substantially horizontally disposed inlet line (10A) receives the stream of fluid and is designed to effect two phase laminar flow at the outlet (51) of the inlet line (10A). The two phase laminar flow has a substantially horizontally disposed interface (51A) that divides the stream into an upper part (55) containing the lighter supercritical solvent which floats on a lower part (56) containing the heavier deasphalted oil.
L'invention porte sur un appareil de séparation d'un solvant d'avec un courant de solvant et de pétrole désasphalté produit lors d'un processus de désasphaltage. Ledit appareil comporte une conduite d'admission (1) recevant le courant et conçue et réalisée pour produire un courant liquide (10) de solvant supercritique et de pétrole désasphalté. Une conduite d'amenée sensiblement horizontale (10A) recevant le courant liquide est conçue pour produire un écoulement laminaire en deux phases à la sortie (51) de la conduite d'amenée (10A). L'écoulement laminaire en deux phases présente une interface (51A) sensiblement horizontale divisant le courant en une partie supérieure (55) de fluide supercritique flottant sur une partie inférieure (56) de pétrole désasphalté.
